2014年干旱背景下铁岭市粮食增产的农业气象条件评价

Agricultural Meteorological Conditions Evaluation of Grainproduction Under Arid Background in Tieling City in 2014

利用铁岭市4个国家级气象观测站实时观测数据、国家级和省级农业气象观测站数据及同期历史资料,对铁岭市玉米、水稻主栽作物生长季内的农业气象条件进行分析。结果表明:2014年铁岭市农作物生长季光热充足,对作物生长及产量形成有利,水稻病虫害发生程度较轻,利于丰产;虽然盛夏铁岭市大部地区降水量显著偏少,出现严重伏旱,但由于前期土壤饱和及"及时雨"助力粮食总产量首次超过450万t,实现了铁岭市粮食生产连续11年增产。

According to four real-time observation data of national meteorological observatory in Tieling,national and provincial agricultural meteorological station data, historical data during the same period,this paper analyzed the agricultural meteorological conditions of corn and rice. The results showed that Tieling＇s agricultural meteorological conditions in crop growth season in 2014 had adequate solar and hot resources ,which benefited to the growth and yield of crops. Decreased degree of rice pests also contributes to high yield. Although the summer precipitation of Tieling City was less than normal and we bad serious drought,the early stage of the saturated soil and ＂timely rain＂ boost more than 45 billion kilogram grain output, which achieved Tieling＇s grain production for 11 consecutive years of increase. ~
